After watching the video you posted, I watch the video of the Mike Wallace interview with her in 1959. And it is amazing how consistent (and of course eloquent) she is throughout such a span of time. Truly remarkable woman. I agree. I've watchted the Wallace and Snyder interviews, as well as the Donahue interview (though in fairness, Rand was very ill by the time of the Donahue interview, and she had just lost her husband, so it was hard for her just to do that interview).
Rand's views never waivered - and many of her predictions have come true.
Rand is one of the greatest writers and thinkers of all time. I admire her work more than any other writer - she also helped me to appreciate some literature that I might otherwise have never cared about.
